Celtic assistant manager Johan Mjallby is confident the clubs top players will stay at Parkhead.
The likes of Gary Hooper, Victor Wanyama and Georgios Samaras are being linked with a possible January departure but Mjallby feels the certainty of Champions League football will be enough to keep them in the green and white hoops.
"This should be a great incentive for them to stay here at Celtic and take us forward," said the Swede.
"You never know where it's going to take us.
"If we hadn't gone through and done as well as we have I think maybe some of the players who have done exceptionally well for us would maybe be interested to have another challenge."
He added of striker Hooper, who has recently been linked with Juventus: "I think Gary's got 18 months left on his contract and we're delighted and we want to keep him.
"It's down to Gary and what his targets are and what he's looking for. He's just enjoying playing football just now. He's in a good place."
